Searing the Ahi Tuna

  1. Receive your Bessie Box delivery
  2. Defrost your tuna out of the packaging
  3. Cut steaks into 3 cm chunks.
  4. Place sesame seeds onto a tray and add the tuna chunks. Flip them over until nicely coated on all sides.
  5. Begin heating olive oil and sesame oil on the same pan.
  6. Peel and thinly slice garlic and most of them to the pan. The remaining garlic will be used to season the dressing. Fry garlic until golden (1-2 minutes).
  7. Remove the golden garlic from the pan WITHOUT removing the oil (we used a slotted spoon) and transfer onto a plate.
  8. Return pan to heat and sear tuna in your garlicky oil. Sear for just 10-20 seconds per side. (Note: your tuna will be raw in the centre, that’s what we’re looking for!)

To Make the Asian Dressing

  1. Peel and grate ginger.
  2. Add ginger to a bowl with soy sauce, 1 teaspoon of sesame oil, and the remaining garlic. Add a squeeze of lemon juice and then stir to combine. Add more lemon juice to taste.
  3. Finely slice a spring onion or scallion and set aside. 


  1. Cut your seared tuna into slices (1 cm thick).
  2. Drizzle Asian dressing and garlic chips on top, red chili, cilantro leaves, finely sliced scallion, and a drizzle of olive oil to finish.
